Codeine Conversion Chemistry

[mrbigsexy]

I've seen alot of hypothetical chemistry out there about making oxycodone, or oxymorphone, or some other unexpected opiate from codeine or some whacked out thing like that through extensive reactions and stuff.

I'm not a chemistry major, however I do have a basic background in chemistry and can follow some simple procedures. My question is this: Assuming you could buy 15grams of codeine for $100 (in tablet form), would there be any practical conversion to do with it?

Basically what I'm probing here is to see if it's practical to buy this much codeine, and efficiently turn it into something better, while still maintaining some kind of efficiency. And by practical I mean meets or beats market price of the target chemical.

Assume the one-time fee of equipment to be negligible. The only cost is that of chemicals, filter paper, reagents, etc.

Any interesting responses are much appreciated, or any references to go look at would be good too, thanks!
